Steward Health Care is owned by New York-based Cerberus Capital Management that also owns DynCorp International a private army hired by the United States for international operations in Iraq, Afghanistan, Bosnia and other war zones.
In the 1990s two of its employees were found to have kidnapped children for sex slavery in Bosnia. In Iraq the company was found by US auditors to have wasted millions in unauthorised works including building a swimming pool for Iraqi officials.
